A power supply for guitar pedals is a crucial component that provides the necessary electrical power to run your effects pedals. Most pedals require a specific voltage (usually 9V, 12V, or 18V), and a quality power supply ensures that each pedal receives the correct power for optimal performance. Using the right power supply prevents unwanted noise, hum, or damage to your pedals.

There are two main types of power supplies: single-output and multi-output. Single-output power supplies provide power to one pedal, while multi-output supplies can power several pedals at once, often with isolated outputs to reduce interference between pedals. Popular options include the Voodoo Lab Pedal Power and the Truetone 1 Spot. These power supplies help simplify pedalboard setups by keeping everything powered with fewer cables and offering reliable, consistent performance for gigging musicians.
